He took his GCSE exams last week. He'll perform at Glastonbury for the first time this week.
Eli Crossley, a 16-year-old musician, will be one of the festival's youngest performers ever when he performs with his band, Askew.
And he's doing it despite the muscle-wasting illness that has kept him in a wheelchair for the past 12 months.
He doesn't appear to be troubled by the enormity of the event.
He chuckles over the phone from his home in London, a week before the festival, "I've got three exams left, and then we've got this little concert.".
Eli suffers from Duchenne muscular dystrophy, an incurable disease that weakens his muscles over time.
His big break came almost by accident when he appeared on BBC Breakfast to discuss his condition earlier this year.
The adolescent was demonstrating a novel piece of technology known as the Smart Suit that is hoped will enable him to maintain use of his upper body as he ages.
He was asked how comfortable it was to wear the device, to which he responded, "Very comfortable, and I hope it will help me in fulfilling my dream of playing Glastonbury. ".
We are joined on the call by his mother, Emily Reuben. She chuckles, "I don't think anyone expected you to mention Glastonbury.
The entire thing just sort of came out and became popular. I was awestruck. You make your aspirations public. ".
It didn't take long for social media to take up the cause and start a petition asking festival director Emily Eavis to book a slot for Eli and his band.
The requests slowed down after a brief burst of activity, though. Then, a parent at Eli's school witnessed Askew acting in a term-ending talent show.
That parent just so happened to be Island Records' Jon Turner. Calls were made the following morning to Eavis and her husband Nick Dewey, and the wheels started turning.
They expressed their desire to have Eli after viewing his video, Ms. Reuben relates.
The group's parents received a coded message from her on WhatsApp that evening reading, "Major news incoming. Soon after, Eli began calling his bandmates, including Alfie, 15, Freddie, Jay, and Will, 16, who are all in the band.
Will, a guitar player, says, "I didn't believe him at all. "I figured it was a small joke. ".
The information eventually became real to me.
Will is a relatively new member of the group, and he remarked, "But I've never played a gig before," Eli relates.
"And I said, "Yeah, well, mate, you're playing Glastonbury now. '".
Second guitarist Jay admits some nervousness, "We've never played anything this big.".
"The only places we've really played were small bars and in front of our parents, etc. We never anticipated being here. ".
Even Eli's confidence wavers when asked how he feels about the show.
"I'm incredibly excited about it while also being terrified about it. ".
However, the band already has the endorsement of one well-known fan, actor Eddie Marsan, who pleaded with festival goers to attend their set.
On Twitter, he said of Eli, "Eli is not only a remarkable young man, he's a phenomenal musician.
His band, Askew, put on an amazing performance when I saw them in Paris. They'll totally destroy Glastonbury. ".
On Friday at 17:30 BST, the band will perform on the intimate and guarded Rabbit Hole stage, which is located underground and requires patrons to solve a riddle to gain entry.
Before being released for the rest of the weekend, they will perform a 30-minute set that combines original songs like Rosemary and Last with covers of Queen's Crazy Little Thing Called Love and Oasis' Supersonic. As Eli puts it, they will also play "a few crowd-pleasers to make sure everybody stays put.".
Eli is adamant about going to see Royal Blood at the Pyramid Stage, but his mother has made it clear that she will be watching Sir Elton John on Sunday night.
She will then return to her regular job managing Duchenne UK, the nonprofit organization she founded after Eli was given a muscular dystrophy diagnosis 13 years ago. Her three-year-old child might not live to be twenty at the time, it was said.
She and co-founder Alex Johnson have raised more than £17 million, which has been used to support clinical trials across the UK, partially fund 34 positions for physicians and nurses, develop guidelines for the care of Duchenne patients, and conduct research into how technology can assist these individuals. King Charles recently presented OBEs to both women.
They conducted research that eventually led to Eli's first appearance on BBC Breakfast, where he talked about the motor-assisted suit that will enable him to keep playing the guitar once his arm muscles start to deteriorate.
According to her, wearing the suit will allow you to "brush your teeth, hug your mother, or raise your arm in class. Everything that seems small but is actually very significant.
They have 10 prototypes under development and hope to make the suit widely available in three years with funding from the Postcode Lottery. This will not only benefit children with muscular dystrophy but also those with other conditions like spinal injuries.
She is an inspiration to many people worldwide, not just to me, claims Eli.
His mother undoubtedly has the same sentiments toward her son.
I simply cannot believe it. He had a dream, and we never in a million years imagined it would ever come true," she claims.
These boys put in a lot of practice and hard work. They will certainly succeed, I know it.
